project idea.. how is it??

i was thinking of a project... accessing an application through a wi-fi enabled device...

the main idea here is to provide the user the facility to add or remove contents from the database...
for example- suppose we are in a restaurant then we should be able to enable the device and access the application .. like browse the menu, order and pay the bill through a device..may be mobile phone or laptop or any other device...

so my question is ... is this a good idea?? :?:
please help me with your inputs...
